Share Price Drop and Market Read
ADR fell ~3% after hours as US September CPI (3.4% YoY) reignited Fed rate hike bets, pressuring all Asian tech names. TSMC's own guidance and margin beat consensus; the selloff reflects macro rate repricing, not fundamental weakness.
TSMC's own numbers are clean. The rate environment is the variable — not the business.
